What is the equation of the line that passes through the point (5,3) and has a slope of -1/5 ?
deff fn [24]

Answer: y=-1/5x+4

Step-by-step explanation: use the equation y=mx+b (x,y)->(5,3) 5 is an x value and 3 is a y value so you want to plug in these values into the equation. 3=-1/5(5)+b. We already know our slope so just plug it into m. Now multiply -1/5 and 5 which is -1. 3=-1+b you want to isolate b so you can find the intercept. Add one to both sides so it cancels out. 4=b we found our y-intercept so we can write the equation now. y=-1/5x+4

It’s a easy mathswatch questionnnnn helpppppp meeeeeeeee
pychu [463]

Answer:

15, 6 and - 3

Step-by-step explanation:

Given x - y = 3 , then

(a)

5(x - y) = 5(3) = 15

(b)

2x - 2y ← factor out 2 from each term

= 2(x - y) = 2(3) = 6

(c)

y - x ← factor out - 1 from each term

= - 1(x - y) = - 1(3) = - 3
